I have a Dell Inspiron 7757 laptop with a factory-installed 16.04. As I used to work on Windows, I tried to change key bindings to more familiar ones. For example, I wanted to use Super + L to lock the screen and Super + D to minimize all windows.

I changed key bindings in System Settings app but the desired bindings won't work. Meanwhile when I press Ctrl + Alt + L, the workstation locks! It's very annoying because in the software I use (Intellij IDEA) this binding has a different meaning.

The same goes for Super + D. It doesn't work, but Ctrl + Alt + D does its work instead.

The most intriguing is that Super + T which I assigned to 'Launch Terminal' action works properly.

Any ideas?

  • Did you check Settings -> Keyboard to make sure that you don't have multiple keybindings set for each?

  • Yeah, I've checked. I also checked the bindings in dconf Editor. There are single values for each. Commented Jun 11, 2018 at 17:06

Exploring related questions here, I found the answer on SO. Just install CompizConfig Settings Manager and look for additional key bindings in Ubuntu Unity Plugin section. You might remove those bindings or change them according to your needs.
